Role of Caustic Addition in Bitumen-Clay Interactions [PDF]

, 2015
Coating of bitumen by clays, known as slime coating, is detrimental to bitumen recovery from oil sands using the warm slurry extn. process. Sodium hydroxide (caustic) is added to the extn.

Stabilization of an earthen material with Tung oil: compaction, strength and hydrophobic enhancement [PDF]

, 2021
Earthen construction generates interest due to its environmental and economic advantages such as low embodied energy, thermal comfort and low construction cost. Two challenges, namely durability and strength, hinder its application.

The influence of irrigation with Lake Kinneret water on the chemistry of soils in the headwater basin

Soil Science Society of America Journal, Volume 89, Issue 3, May/June 2025.
Abstract The farming areas in the catchment of Lake Kinneret basin are irrigated with Dan Spring waters, characterized by a concentration of 10 mg/L of Cl. Climate change simulation predicts that by the year 2050, the flow of the headwater springs will drop by 20%, a finding that poses a significant threat to the future of farming in the basin.

Effect of vegetation cover and soil moisture on water repellency persistence of drained peat soils

Biologia
Peatlands play an essential role in the environment and their conservation requires knowledge of water-related processes. Their hydrophobicity is an important factor influencing the flow of water in soils.

The Relationship between Soil Moisture and Soil Water Repellency Persistence in Hydrophobic Soils

, 2020
In this work, we modelled the response of soil water repellency (SWR) persistence to the decrease in moisture in drying soils, and we explored the implication of soil particle size distribution and specific surface area on the SWR severity and ...

Minimal Soil Impacts of Caesalpinia decapetala Invasion in South Africa's Vhembe Biosphere Reserve

African Journal of Ecology, Volume 63, Issue 2, March 2025.
ABSTRACT We assessed the effects of Caesalpinia decapetala (Roth) Alston invasion on soil physical properties over 3 summer months in Vhembe Biosphere Reserve, South Africa. Topsoils were collected beneath replicated invaded and uninvaded conditions and assessed for soil moisture, water repellency, penetration resistance, infiltration and hydraulic ...

Droplet infiltration dynamics and soil wettability related to soil organic matter of soil aggregate coatings and interiors

Journal of Hydrology and Hydromechanics, 2016
The organo-mineral coatings of soil aggregates, cracks, and biopores control sorption and macropore-matrix exchange during preferential flow, in particular in the clay-illuvial Bt-horizon of Luvisols.

Water repellency in forest soils affected by fires and agricultural soils with different agricultural management and abandonment

Cuadernos de Investigación Geográfica, 2013
Soil water repellency determines the water available in the soil system, the runoff generation and the geomorphologic processes. This study examines the soil wettability during the summer of 2008 and 2009 in forest soils with different fire history, and ...

La repelencia al agua inducida por el fuego está controlada por pequeñas variaciones en las propiedades del suelo [PDF]

, 2014
Fire induced soil water repellency (WR) is controlled by many different factors (temperature reached, amount and type of fuel, etc.). Soil properties may determine the occurrence and intensity of this property in burned soils.

Biochar impacts on soil moisture retention and respiration in a coarse‐textured soil under dry conditions

Soil Science Society of America Journal, Volume 88, Issue 6, Page 1919-1931, November/December 2024.
Abstract The growing water scarcity jeopardizes crop production for global food security, a problem poised to worsen under climate change–induced drought. Amending soils with locally derived biochar from pyrolyzed agricultural residues may enhance soil moisture retention and resilience, in addition to climate change mitigation.
